Abstract (en)

[origin: EP3288052A1] Provided is a dye-sensitized solar cell having high conversion efficiency. The dye-sensitized solar cell is a dye-sensitized solar cell in which a photoelectrode and a counter electrode are disposed opposite to each other via an electrolyte layer; (1) the photoelectrode comprising a titanium material, a blocking layer formed on the titanium material, and a porous titanium oxide layer containing a dye sensitizing agent formed on the blocking layer; and (2) the counter electrode comprising a transparent conductive glass or transparent conductive film coated with an electrochemical-reduction catalyst layer.
